Abstract：Objective To investigate the clinical effect of short-segment pedicle screw fixation for the treat-ment of thoracolumbar burst fracture and to provide a reference for clinical treatment .Methods 68 patients with tho-racolumbar fracture were selected from January 2009 to December 2013 and randomly divided into the observation group and the control group accordding to the digital table .The control group was treated with short-segment pedicle screw fixation and the observation group was treated with the same treatment combined with the additional fixation . The sagittal Cobb angle , the leading edge of vertebral height ratio , VAS pain scores , the American Spinal injury As-sociation( ASIA) neurological rating were recorded in all patients before and after the treatment and compared between the two groups after a follow-up of one year .Results After one year of the treatment , Cobb angle of the observation group was significantly lower than that of the control group [ ( 6.19 ±1.87 ) °vs ( 7.86 ±2.76 ) °, t=6.247 , P=0.008 ];Vertebral leading edge height ratio of the observation group (94.22 ±10.37 )%was significantly higher than that of the control group (86.55 ±9.93)%(t=4.247,P=0.018); VAS score of the observation group(0.97 ± 0.17) was significantly lower than that of the control group (1.69 ±0.66)(t=3.553, P=0.024); There was no significant difference in ASIA rating between the two groups ( Z=1.076 , P=0.246 ) .Conclusion Short-segment pedicle screw fixation in combination with vertebral fixation has a good clinical effect on thoracolumbar burst fractures .
